When I'm at home and don't feel metal enough to warm up the 100w stack, I have a Line6 guitar port (I think they call it studio POd or something now) jacked into the USB on my computer, and that goes out to my studio monitors on my desk. Makes it fun and easy to play with tones (dragging and dropping amp heads and stomp boxes with a mouse is much easier than fighting with a POD interface) and jamming along with favorite tunes is easy that way as well. My house is in the US, but I also have a flat in Germany, and my little USB pod thing goes with me.

For that money I suggest the Blackstar HT-5, 5 watts and can get pretty loud if you want to. However, sounds fantastic on low volumes aswell. Bought one 6 months ago and I´m really pleased how that turned out and it can play anything.
